I am an author of over two hundred books, mainly for young people, but also, lately, for adults. In my non-fiction I have written on subjects as diverse as sharks, robots, asteroids, flying reptiles and chocolate. I also write novels and stories in the genres of science fiction, mystery, historical and horror. I write online, interactive stories for Fiction Express, two of which have won awards. I won the Association for Science Education award in 2021 for my non-fiction book Think Like a Scientist. My horror novel, Soul Shadows, was shortlisted for the Falkirk Red Book Award.
